Hello everyone.
00:01
In this question we have given that a proton is released from rest in an electric field.
00:12
We have to tell whether the quantities electric potential, potential energy, kinetic energy and total energy whether these quantities increases, decreases or remain unchanged.
00:27
First one.
00:29
First one, potential.
00:35
As we know that, proton is a positive charge.
00:39
And if we left it in an external electric field, it will move in the direction of electric field.
00:47
We also know that in the direction of electric field, the value of potential decreases.
00:53
So at the location of proton, the value of potential will decrease.
01:03
So our answer will be decreases.
01:10
Now second one, potential energy.
01:13
As we know that when we left a proton in an uniform electric field, it will move in the direction of electric field and it accelerate...
